Hoston welding table welding layout table

The Hoston welding/layout table is a precision fixture table designed for welding, positioning and layout work. It features a grid of accurately machined holes for locating pins and clamps and is offered in three series (D16, D22, D28) with different hole diameters and grid spacings.

D16: hole diameter ≈ φ16.065–φ16.149 mm, grid spacing 50 × 50 mm (L1 = 50 ± 0.05 mm). D22: hole diameter ≈ φ22 mm, grid spacing 75 × 75 mm (L1 = 75 ± 0.05 mm). D28: hole diameter ≈ φ28.065–φ28.149 mm, grid spacing 100 × 100 mm (L1 = 100 ± 0.05 mm).

Hole-spacing tolerance: ±0.05 mm (per series L1). Flatness: 0.1 mm per 1000 mm. Verticality: 0.1 mm per 200 mm. Aperture tolerances for D16 and D28 series are provided in the product parameters.

D16 series surface roughness: RA 1.6. D28 series surface roughness: RA 3.2. Tables are nitrided with hardness roughly HV450–HV630 on the treated surface.

Standard tabletop load bearing is 2 tonnes (2T). Frame bearing capacity is 5 tonnes (5T). Always respect these limits and distribute heavy loads evenly.

Sizes vary by series; examples from the spec: PT-1010 (1000 × 1000 × 200 mm), PT-1212 (1200 × 1200 × 200 mm), PT-1515 (1500 × 1500 × 200 mm), PT-4020 (4000 × 2000 × 200 mm). D16 examples include PT-1010D (1000 × 1000 × 100 mm), PT-1515D (1500 × 1500 × 100 mm), PT-2412D (2400 × 1200 × 100 mm). Contact the supplier for the full size/weight list.

Yes — custom sizes, hole patterns, hole counts, special frame options and additional machining are commonly available. Contact the manufacturer or distributor with your requirements for a quotation.

The product specification lists a nitrided, hardened surface (HV450–HV630). For exact base-material (cast iron, steel grade, etc.) and full material certificates, please request details from the manufacturer.

Yes. The grid holes are designed for locating pins, clamps and modular fixturing sized to the series nominal diameters (≈16 mm, 22 mm or 28 mm). Use clamps and pins matching the table series for secure fixturing.

Yes, the table is designed for welding applications, but excessive concentrated heat can damage the surface. Use sacrificial plates, heat sinks, or grounding practices as needed and avoid prolonged localized heating to protect the nitrided layer.

Use appropriate lifting equipment rated for the table weight/size and lift from the frame or specified lifting points — do not lift by the tabletop only. For large tables, use multiple lift points and follow the manufacturer's installation instructions to prevent distortion or damage.

Keep the surface clean and dry, remove welding spatter and debris promptly, apply a light protective oil to prevent corrosion if needed, and avoid abrasive grinding directly on the surface. Periodically inspect hole wear and flatness; perform rework or re-nitriding through the manufacturer if necessary.

Yes — most suppliers can provide flatness inspection and certification or supply the table with factory calibration documentation on request. Ask the manufacturer for inspection reports or certification options.

Common accessories include locating pins, various clamp sets, angle stops, T-slots/adapters, leveling feet, casters, sacrificial plates, welding screens, and modular fixture kits. Availability depends on the supplier.

Lead time, packaging and warranty vary by table size, customization and order quantity. Contact the seller or Hoston representative for current lead times, shipping packaging options and warranty terms for your specific configuration.
